Control of Structure Why do elements and compounds adopt one structure as opposed to another?

Thermodynamics Review: G = H - TS Bond Strength Favored by strong bonds. Freedom of Movement Favored by more particles. Temperature Control?

Thermodynamics Review: G = H - TS Bond Strength Favored by strong bonds. Freedom of Movement Favored by more particles. Example: Cl-Cl vs. Cl Cl Cl-Cl bond strength = 242 kJ/mol So (Cl) = 165 J/Kmol So (Cl2) = 223 J/Kmol

Bonding Concerns and Trends: Number of bonds Type of bonds: sigma vs. pi

Number of Bonds Possible: F, O

Number of Bonds Possible: N, C

Lewis Base Activity Expands # Bonds
